BY Z 2 L g Patented June 13, 1944 UNITED STATES PATENT OFFICE I a v 2,351,402 I v SPLICING oLAMP Ernest E. Clark, Lubbock, Tex. Application May 20, 1943, Serial No. 487,795

4 Claims;

This invention r'elatesto cable-splicing jigs or clamps, the primary object of the invention being to provide means for securely holding the cable, while it is being spliced.

An important object of the invention is to provide a jig or clamp which will securely hold the wire cable which is being spliced, around a tnimble to insure the proper fit between the cable and thimble, after the splice has been completed.

Another object of the invention is to provide a device of this character which may be rotated, changing the position of the cable, to facilitate the splicing operation, and eliminate the necessity of releasing the cable from the jig or clamp, in order to change the position of the cable.

Still another object of the invention is to provide a device of this character which may be securely held in a vise, or permanently secured to a work bench.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is an elevational view of a jig or clamp, constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the body portion of the jig or clamp.

Figure 3 is a sectional view taken on line 3-3 of Fig. 1.

Figure 4 is a sectional view taken on line 4-4 of Fig. 1.

Figure 5 is a sectional view taken on line 55 of Fig. 1.

Referring to the drawing in detail, the jig or clamp, embodies a supporting sleeve 5 which is formed with notches 6 disposed in one end thereof. The reference character 1 designates a wide plate that is secured to the supporting sleeve 5 and is adapted to be held between the jaws of a vise, should it be desired to use the device in connection with a vise. An opening is also provided in the wide plate I, for the reception of a securing bolt, whereby the device may be permanently secured to a work-bench.

The body portion of the jig or clamp is indicated by the reference character 8, the body portion being tubular in formation, one end thereof being formed with an opening to permit the threaded shank 9 of the jaw-supportin member, to be extended therethrough. Th body portion is of a diameter to closely fit within the supporting sleeve 5, as clearly shown by Fig. 2. and since the body portion is appreciably longer than the supporting sleeve, a space is provided between one end of the supporting sleeve and the band In which is secured to the body portion adjacent to one end thereof, for the reception of the coiled spring II which acts to normally urge the body portion 8 through the supporting sleeve, in one direction. A lug indicated by the reference character I2 is secured on the body portion, adjacent to the notches B, and is shaped so that it will fit within the notches 6, holding the body portion against rotary movement with respect to the supporting sleeve, under normal conditions.

Thus it will be seen that as the coiled spring moves the body portion through the sleeve, the lug 12 will be urged into one of the notches to prevent rotary movement of the body portion.

The jaw-supporting member indicated at H. embodies spaced arms I4, between which the jaws l5 are pivotally supported. These jaws I5 are curved to conform to the shape of the usual cablecovered thimble l5, around which the cable is secured, during the splicing of the cable. A nut indicated at I! is mounted on the threaded portion of the shank 9, and engages one end of the body portion 8, with the result that when the nut I1 is rotated in one direction, the jaw-supporting member will be drawn into the body portion and the jaws l5 will be closed tightly around the cable and thimble held between the jaws. The cable is now in a position to be readily spliced, and should it become desirable to rotate the end of the cable being spliced, slightly, to facilitate the splicing operation, it is only necessary to pull the body portion 8 against the action of the coiled spring H, to disengage the lug I2 .and notch of the supporting sleev 5, in which the lug is disposed. The body portion 8 ma now be rotated to the desired position, and when the body portion is released, the coiled spring II will act to return the body portion to a position where the lug will move within a notch, securely holding the body portion against rotation within the sup-.

porting sleeve.

In view of the foregoing, it is believed that the construction and operation of my jig or clamp, will be clear, and further description as to the use of the device is believed unnecessary.

What is claimed is:

1. In a cable-splicing clamp, a supporting sleeve having open ends and having notches formed in one end thereof, a tubular body portion posi- 2v ,351,4o a jaw supporting member mounted within the tioned within the sleeve and adapted to slide therethrough, a lug on the body portion and adapted to fit within the notches, normally holding the body portion against rotation within the sleeve, yieldable means adapted to urge the body portion in one direction and hold the lug in one of said notches, clamping jaws supported b said body portion, and means adapted to move said jaws into clamping relation with respect to each other.

2. In a. cable-splicing clamp, a supporting sleeve, a plate extending from said sleeve and adapted to be secured to a supporting surface, a,

tubular body portion having an open end, mount ed for sliding movement within said sleeve, means for securing the body portion againstrotarymove; ment within said sleeve, clamping jaws extendin from the open end of the body portion, and means for drawing said jaws into the open end of the body portion and in contact with the end wall of thetbody portion, wherebythe. jaws. are moved toward each otherto clamp acable.

3. In a. cable-splicing clamp, a, sleeve. adapted, to be secured to asupport said sleeve having. open ends, a, tubular body, portion mounted, for

slidin and rotarymoyement withinthe sleeve,

body portion, pivoted jaws mounted on the jaw supporting member, said jaws extending from one end thereof, means for moving the jaws into engagement with one end of the body portion whereby said jaws are closed around a cable in ripping relation therewith, and means for securing the body portion against rotary movement within the sleeve.

4, In a cable-splicing-clarnp, alsupporting sleeve having open ends, said. sleeve having, substantially V-shaped notches formed in one end thereof, a tubular body portion slidably mounted within the sleeve, a lug shaped to fit within said notches, disposed adjacent to one end of the body portion and, adapted to fit in said notches, re-' stricting rotary movement of the body portion and sleeve-withrespectto each other, yieldable means on, thebody portion adapted to urge'the body portion longitudinally of the sleeve, seating the lug in anotch or the-sleeve, jawssupported by the body portion, and said. jaws; being. extended, beyondgone end. of. the ,bOdy portionv and adapted;

to grip a cable.
